FIREPLACE-BLOWER.

SPECIFICATION forming part of Letters Patent No. 779,114, dated January 3, 1905. Application filed December 23, 1903. Serial No. 186,374.

T0 all whom, t may concern.-

Be it known that I, HARRY BoRRow, a subject of the King of Great Britain, residing at East Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Fireplace-Blowers, of which the following is a specification.

This invention relates to a combined hood and blower for open fireplaces. and has for its object to produce an improved device of the kind stated characterized particularly by the fact that it may be so adjusted as to entirely close the fireplace, except under the grate, so as to act as a blower, and that it may also be adjusted or opened out to act as ahood, which will expose the fire, but at the same time prev ent the escape of smoke from the front of the fireplace.

Figure 1 is a side view of the article detached. Fig. 2 is a section showing the same applied to a fireplace. Fig. 3 isafront view ofa modification suitable for an arched fireplace. Fig. 4 is a section on the line 4 4 of Fig. 3.

Referring to the drawings, and specifically to Figs. 1 and 2, the device includes a metal plate 6, forming the hood or main portion of the device, and this has at its side edges flanges 7, which work inside the side walls of the fireplace, (indicated at 8.) At the top edge of the plate is a flange 9, which fits up under the top of the fireplace, so as to assist in holding the blower or hood in place. The plate is preferably formed of metal and may be ornamented as fancy or desire may indicate. The plate so forming the blower or hood is supported upon standards 10, which are made of metal rods or heavy wire shaped or bent at the lower ends to produce forkswhich fit over the top bar of the grate, as shown at 12. These supports orstandards work through holes or loops 13, produced at the upper and lower ends of guide-bars 14, and both the guide-bars and the standards are connected at the Lipper end to crossed arms 16, respectively projecting from coiled springs 17. The purpose and effect of this is to allow these supports a limited vertical movement or adjustment with respect to the guide-bars and the blower, so that when the blower or hood is put in place by pressing the arms 16 together the forked lower ends of the supporting-standards are lifted above the grate-bar and when released snap down over the grate-bar, so as to hold the device in place. This construction greatly facilitates the insertion or removal ofthe device frorn a lireplace.- Connecting the tops of the guide-bars 14 is a hinge or pivot-rod 13 for the metal plate. This rod is fastened to the tops of the guide-bars and is thence first offset backwardly, as at 18a, so as to bring it behind the line of the fireplace-opening, and it extends thence loosely through the flanges 7 at the top thereof and thence behind the top edge of the plate to the middle, where the rod is joined to a lever 19, the upper arm of which extends through the plate and back of the arch of the fireplace, where it holds the devices in place in all positions. The other arm of the lever extends downwardly to a iiexible joint at 20 with the end of a curved handle-bar 21. This handle-bar extends through a slot 22 in the front of the plate and works in contact with the upper end of said slot. Extending from the handle is a spring rack-bar 23, which bears in yielding contact with the lower end of the slot, where its notches 23 may be engaged.

The rod 18 acts as a pivot on which the blower may be swung in or out. i This action is effected by manipulation of the handle 21.' By disengaging the rack-bar 23 the handle may be raised or lowered on the point 20 as a pivot and by the sliding engagement of its upper portion against the top of the slot will raise or lower the plate accordingly, which when brought to the desired yinclination is fixed by engaging the rack-bar at the lower end of the slot. By virtue of its connection with the lever 19 the handle acts in conjunction therewith to produce a leverage sufficient to enable the blower-plate to be raised or lowered. W hen lowered ,to the full extent, it closes down against the grate-bars and forms a blower, and it may be raised to any desired extent to produce a hood, the extent of elevation permitted being governed by the draft, in which case it acts as an effective smoke-preventer, thereby avoiding the nuisance of a smoky grate.

The modification shown in Figs. 3 and L is similar in operation; but its construction is IOO modiiied to conform to an arched fireplace. It has a relatively stationary top portion 24, which is shaped to lit the curve ot' the arch and when in place is engaged at its edges behind the same, sothat it will not fall out or in. 1t is supported upon yielding standards in all respects similar to those hereinbefore described, so that it may be readily inserted or removed. The swinging plate 25 is hinged upon a rod at the top and has an operatinghandle, as hereinbefore described. and may be closed down or opened up in similar manner.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the blower-plate, of the extensible spring-actuated standards supporting the same.

2. The combination with the side supporting-standards, of a bar extending across between the standards at the top, a plate hinged upon the bar and depending between the standards, and an operating-handle pivotally connected to the bar and extending through the plate and having a rack engageable with the plate to hold the same at adjustment.

3. The combination with the 'supportingstandards at the side, of the curved lixed top piece, the plate hinged thereto and hanging thereunder, and means to vary the adjustment ofthe hinged plate, substantially as described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.

HARRY BORROW.
